Collaboration, The ALEPH and Edgecock, R. (2009) Measurement of Z-pair production in e+e−collisions and constraints on anomalous neutral gauge couplings. Journal of High Energy Physics, 2009 (04). p. 124. ISSN 1029-8479

The ZZ production cross section is measured from a data sample corresponding to a total integrated luminosity of 452 pb−1, collected by the ALEPH experiment at LEP at centre-of-mass energies from 192 to 209 GeV. Individual cross sections, extracted at six centre-of-mass energies, are found to be in agreement with Standard Model calculations. The results are used to set limits on anomalous neutral gauge couplings.
